How do you optimize Angular applications for faster load times?

Short answer: Use Ahead-of-Time (AOT) compilation for faster rendering.

Explain a bit more

Enable production builds (ng build --prod) with optimizations: Minification Tree shaking Dead code elimination Use lazy loading for feature modules. Bundle analysis: Use tools like source-map-explorer to find large bundles. Use Angular’s built-in caching and service workers (via Angular PWA) for offline and faster repeat loads. Optimize images and assets (compress, lazy load). Use OnPush change detection for components to reduce unnecessary UI updates. Avoid memory leaks by unsubscribing from observables. Use trackBy function with *ngFor to optimize DOM updates.

Real-world example (ShopNest)

ShopNest admin can be built in Angular with modules/components, services for API calls, and reactive forms for product edit.

Say this in the interview

1. Define — one clear sentence (the short answer above).
2. Example — relate it to a project like ShopNest or your real work.
3. Trade-off — when you would not use it.
